Blochemical monitoring of genetic collections of strawberry in NCFSCHVW and CEBS

Abstract

The article presents the generalized results of long-term research (2012-2020) of the assessment of the chemical composition of strawberries of 90 varieties of various ecological and geographical origin, growing in the genetic collections of NCFSCHVW and CEBS (branch of VIR). The advantage of varieties of Italian selection, as well as Russian (NCFSCHVW, CEBS) is the increased content of soluble solids and sugars. The varieties obtained in France and Russia are characterized by a high level of accumulation of vitamin C. The largest amount of vitamin P is contained in strawberries of American varieties. According to the results of a study of five groups of strawberry varieties of different ripening periods, it was found that varieties of an early ripening period accumulate less soluble solids and sugars, and late-ripening ones stand out with a high content of soluble solids, sugars, vitamins C and P. Highlighted varieties that are the sources of high soluble solids content (9-9.9%), sugars (6.8-7.5%), acids (1.0-1.28%), pectin substances (0.7-0.79%), vitamin C ( 65.1-74.5 mg / 100 g), vitamin P (90.0-120.1 mg / 100 g) and anthocyanins (92.0-127.0 mg / 100 g).
